3 Claims. 1

This invention relates to new and useful improvements in window frame and sash structures.

According to the invention, a Window frame is provided having separate vertical slideways for each of more than two, preferably three, independently raisable and lowerable sashes, such slideways at the sides of the window frame; and opposite these sashes, and preferably outward therefrom, is, a larger sash for lling the entire window frame opening, said larger sash being readily removable from the window frame by withdrawal into the room past the sliding sashes.

Said outer sash, having one or more glass paned sections, is thus removable to allow of easy and safe washing of the outer surfaces of such panes, or for repair or replacement of the sash. f

Because of more than two independently raisable and lowerable sashes as above, these can be variously placed at a succession of different levels relative to each other to permit easy and safe access to the panes thereof for successive washing of the outer surfaces of their panes, from the inside of the room.

Another feature is a pivotally mounted auxiliary sash carried by the outer sash, and thus carried opposite a lowermost open section or subdivision of the outer sash; said auxiliary sash adapted to act as a swingably adjustable air inlet means and so modiable as a Ventilating agent. The direction of ow of the Ventilating air current is controlled also by the relative heights at which the sliding sashes may be positioned.

.A further feature of the invention is the elimination of the necessity for sash cords and weights or for spring torsion substitutes, this feature involving the use of very light weight sashes, the light weight of each sash in considerable part resulting from the fact that more than two sliding sashes are present; in combination with a simple and practicable resiliently mounted structure carrying the three slideways at one side o-f the window opening for all the sliding sashes, and an associated means for adjusting the resilient action of such mounting, to vary its thrust relative to the slideways for the sliding sashes, thereby nicely to predetermine the frictional engagement between said sashes and their slideways. The resilient means now referred to may also be adjusted if and when desired to permit removal of any or all of the sliding sashes.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and l accompanying drawing, and to 'the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. l is an elevational view looking at the intrior side of a window frame and sash structure constructed in accordance with the present invention.

Fig. 2 is an enlarged horizontal section, taken on the line 2--2 of Fig. 1

Fig. 3 is a similarly enlarged vertical section. taken on the line 3-3 of Fig. 1.

Fig. 4 is a view similar to Fig. 3, but showing a rear arrangement of the parts for a selected kind and degree of ventilation.

Fig. 5 is a slightly enlarged partial vertical section, taken on the line 5 5 of Fig. 3.

Fig. 6 is a view similar to Fig. 4, illustrating a structural modification.

The window frame and sash construction, ac cording to the rst form of the invention shown in Figs. 1` to 5, includes a window frame IIJ having side members II, a cap or top sill I2, and a bottom sill I4.

Three sliding glass paned sashes I5, I5 and I'I are provided to completely close the window frame opening; each such sash preferably of the same height. The heights of these sashes are such that when the sash I5 is at the top of the window frame opening, and the sash I1 is at the bottom of said opening, the sash I6 may be arranged with its top properly overlapping the bottom of the sash I5 and its bottom properly over lapping the top of the sash Il'.

At each side if the window frame three slideways for said sashes are provided by three grooves in a bar or plate shaped to carry four parallel ribs to establish said grooves. One of such plates, marked I8, extends as shown in Fig. 3 from the top to the bottom of the Window frame opening;

and is suitably xed in the recess I9 (Fig. 2) in the window frame.

At the otherside of the window frame, the plate 20, -presenting the three slideways for the adjacent sides of the sashesv I5, I6 and Il, is housed movably in the recess 2l; this plate 2D being adapted to be resiliently urged against the sashes I5, I6 and I'I by way of a long leaf spring 22 behind the plate 2U.

The spring 22 is bowed as indicated in Fig. 2, and its tension is adjustable by spiral adjustment of a pair of screws 24 the heads of which lie beyond the outer sides of a pair of upperand lower arcuate clip's 25 at the exterior of the ad-l jacent side member II of the window frame. The shank of each screw 24 goes through a suitable aperture in its associated clip 25, and thence through and in threaded engagement with an internally threaded bushing 26; as shown best in Fig. 2.

The inner ends of said screws bear against the ends of the spring 22, see Figs. 1 and 2, and so by tightening or loosening the screws 26 the frictional grip of the slideways of the' -plates I8 and 20 relative to the sashes I5, II and I1 may be increased or diminished to the desired extent. Also, by fully loosening the screws 24, any or all of the said sashes I5, IS and I1 may be removed whenever desired.

The sash for filling the window frame opening at an outward location comprises a frame 21, which, with its bottom seated on a stepped-down ledge 28 on the bottom sill I4, and while resting against a pair of stops 29 at the opposite sides of the window frame, is held in place by a pair of locking devices each including a slide bolt 30 guided through eyes3I on the frame 21 and having an L-extension 32 constituting a finger piece; whereby the bolts may be entered into suitable keeper recesses in the window frame, as indicate at 33 in Fig. l.

The illustrated outer sash is one for summer time use, and the frame' 21 thereof is shown as having two closures of differing types separated by the cross frame member 34. Such upper closureis a glass pane-36, and such lower closure is a screening 31, the latter bottomed by a cross frame member. The opening below said member 35 is closable by an auxiliary sash comprising a frame 38 carrying a glass pane 39, this frame hinged at its front bottom as at i9 to the front bottom of the frame 2-1 of the outer sash.

Said auxiliary sash, swingable into the plane of the frame 21, is thus retained by a latch of any suitable type, here shown as in the form of a latchplate I pivoted at l2 (Fig. 5) and carrying an offset operating finger piece 43.

The auxiliary frame 33 is thus swingable to the position shown in Fig. 3 to that shown in Fig. 4, or to any selected less angle of inclination from the vertical, toY modify as desired a Ventilating inlet for air additional to that admitted through the screening 31'; theventilating air being further controlled by the relative arrangement of the sliding sashes I5, I and I1, for instance, as shown in Fig. 4, or as shown in Fig. 3. Extreme flexibility of Ventilating control is thereby possible; as, for further example, to admit the Ventilating air at the bottom of the window frame opening, and/or to admit said air at the top of such opening, and/or to admit said air at an intermediate point along the height of such opening.

As a further example, the manner of ventilating may be that indicated by the relative positions.. of the sliding sashes I5', It and I1 of the mod-ication of Fig. 6 (these sashes corresponding respectively to the sashes I5, I6 and I1); it here` being explained that the sole purpose of including Fig. 6 -is to illustrate a further addition which may be made to the summer time outer sash, to wit, the suitable fixation to the latter, at its bottom subdivision openable by the auxiliary Ventilating frame 31 (corresponding to the frame 31), of a supplementary frame 4Q closed by the screening 45.

In` all other respects than that just noted. the structure of Fig. 6 is exactly like that of Figs. 1-5.

For use in the winter time, there may be supplied an outer sash exactly like that of Figs. 1 5, except that in lieu of the screening 31, a glass pane will be in the subdivision of said sash between the cross frame members 34 and 35. Or, for winter time use, to provide complete storm window protection, yet avoid the need for a special winter time outer sash, the outer sash of Figs. 1-5 may have its screening 31 so set therein that the same may be readily removed and a glass pane inserted in substitution therefor.

In order to remove the outer sash, as to facilitate the substitution just referred to, or for the purpose of substituting a special winter time outer sash, or to permit easy and safe washing of the outer surfaces of the glass pane or panes of the outer sash, all that is required is to withdraw the bolts 30 from their keepers, and then, by pull on the handle 32, to swing the top of the outer sash toward the right in Fig. 3, and then the three sliding sashes I5, I6 and I1 all having been fully lowered, to bodily transfer the outer sash to the room interior.

Washing of the outer surfaces of the glass panes of the sashes I5, Io and I1 is also easy and safe. The most convenient procedure is thus to wash the pane of a particular sash I5, IS or I1 while that sash is all the way down in the window frame and the other two of'saidsashes are all the way up in the Window frame; so that, in the case of each of the successive washings of the outer surfaces of the panes of the three sashes I5, I6 and I1the window frame will be open above the sash being washed. Due to the three sliding sashes, such window frame opening not only will always be available during washing, but be of ample size for comfortably reaching in behind the sliding sash at the bottom of the window frame for complete cleaning of. the outer surface of its glass pane.

While I have illustrated and described theI preferred embodiments of my invention, it is to be understood that I'do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
